OK, not Zoot. It's Brew Moore playing "Ergo" from the album Brew Moore in Europe.
I liked Straight 2. "You Go to My Head" - I'd guess mid-1950's with vibes reminiscent of Milt Jackson and guitar reminding me of Barry Galbraith.
Track 1 sounds like Zoot Sims in the early 1950s.
Track 5 is the Gene Krupa Orchestra playing Gerry Mulligan's great composition and arrangement "Disc Jockey Jump".
